To all'whom it may concern 7 r 7 Be it known that 1,5 A ms lVA'rson, a subject ofv the King of England, residing at Youghal, county Cork, Ireland, have invented new and useful Improvements in Processes for Utilizing Sheet-Glass forSurace Decoration, which the following is a specification. I

This invention relates'to a process by which ordinary sheet, rolled, or plateglass may be adapted to surface decoration.

It consists in first making a drawing of the design, then cutting glass to the required I shape and copying the drawing thereon in enamel colors; covered with a transparent film of glass paintefs flux, and stippled, and it may be covered with a prepared powder of crushed opal glass and fiuxJ The glass is then sub-' jected to the heat of a mu'liie furnace to develop and fixthe colors a The glass may then be temporarily glued face down upon the reverse side of the drawing from which it was cut and subsequentl appliedto the wall or panel to be decorate said wall having been previouslyprepared with a white cement for adhesively securing the glass thereto. WVhen the cement has set, the paper may be removed, and the backing will be found to be immovable.

The invention also comprises details which will be more fully described in the following specification As the painting is seen through the glass, the drawing must be made the reverse way to that which it. is to appear when finished, as in type or blocks for printing. The glass is cut to a required shape, as in a lead light or stained glass window, butas the colors are applied in enamel, it is not necessary to out every piece of color separately. The drawing is then-copied in enamel colors, as in porcelain or glass painting, or it may be stenciled or printed.

If a dull surface is required, the opposite side (that is the side presented to the spectator when fixed in position) is covered with 'a thin transparent film of glass painters flux and lightly stippled.

When dry, the surface on which the de- The surface when dry is handle as in ceramic mosaic.

making six parts in all.

. The glass is then placed in a glass painters muflie and fired to an ordinary color heat. When removed from the muiile, the enamels will be found fully developed in color and provided with white hacking having a texture similar to coarsc sandpaper.-

In cases where a highly finished painting is required the addition of the opal glass may be omitted until the artist satisfied with his work. He may strengthen his work and tire it as many times as is; necessary, judging the finished oifect by placing his work on white paper. When quite satisfied the hacking powder may he a-pplied and of glue. In the case of large work, it may then be divided into sections, convenient to panel should have been previously prepared as for mosaic, and to obtain the best effect, the fixing medium between thefoundation and the. glass should be a white cement, such as Parian, Keanes or white lead. When the cement is sufiiciently set, the paper may be removed and the surface made good as in mosaic. hen the-work has set to its maX1- will be found to adhere to the cement so firmly that no piece can be removed except by destroying it. In the case of timber work, it may be applied with thick paint or ordinary oil putty and to metal work by the same materials. i

The advantages claimed are:

Low cost of materials,

. Easy cutting and copying of design,

. Absolute permanence,

Cleanliness,

The wall or inum hardness, the special backing provided.

Its wide range of application ranging from miniature painting to plain Wall surfaces. 7 V r The latter offers great attractions to architects. Any shade of color can be obtained, and if treated as in leaded glass simple and effective designs can be obtained at a very small cost. Sheet glass, tinted and backed, can be made and cut to the required design and fixed by the plasterer as easily as wall tiles. The glass itself is imperishable. The life of the Work is dependent entirely on that of the material, cement, concrete, stone, Wood or metal to which it is attached. As an advertising medium it is superior to enameled iron, no disfigurement through rust or flaking being possible. It can be applied v to every process of decoration, public or domestic, internal or external, and can be cleaned as easily as an ordinary Window pane.

"Having thus described my invention, What I claim and desire to secure by Letters Patent is l. The process of producing surface decorations consisting in first reproducing the design in the desired colors upon one surface of a glass body, then applying a thin film of transparent glass painters flux and, sti pling the film, baking it in a glass painters mutlle, and finally attaching the completed glass to a supporting panel or Wall.

2. The process of producing surface decoration, consisting in applying a design in colors to the back surface of a sheet of glass so as to be seen therethrough, covering the design with a film of glass painters flux, lightly stippling a transparent film of glass painters flux on the front surface of the sheet of glass to provide a dull finish, and firing in a mulfie to develop and fix the colors.

The process of producing surface decoration, consisting in applying a designin colors to a glass surface, covering the design with a film of glass painters flux, applying a thin fihn of transparent glass painters flux to the opposite surface of the glass and stippling-said film, and firing it in a muffle to develop and fix the colors.

l. A decorated glass surface comprising a colored design on one side of the glass protected by a covering of crushed opal glass and glass painters flux, and a stippled film of transparent glass painters flux applied to the opposite side of the glass, the whole'being baked.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
